Repeat form step 6.
This explosive loop transforms a single ping of damage into an apocalyptic chain reaction by turning your life gain directly back into board-wide destruction. While Arcbond places a volatile curse on your creatures—including an indestructible target to anchor the loop—Increasing Vengeance ensures you have the redundancy needed to get the chain rolling. Once the damage starts spreading, Bloodthirsty Conqueror steps in as the engine's heartbeat, triggering life gain for every opponent hurt and instantly feeding right back into Arcbond's next wave.
